Interesting. They may be later driveshafts, not sure where I got them from. You are right about the alignment arrows, the other shafts I have do not have the arrows. Edited by berettajeep - 20 June 2022 at 5:57pm |

If the slip joint splines are worn, vibration can also occur. Check for any free motion either on rotation or side to dide.

Hi guys,
Problem solved. Cheers to you! I undid the rear propeller shaft and aligned the yokes. Was all easy. Tried the same with the front but the splined end were totally frozen. No way to move them. So, decided to drive for now without the shaft and look for a repair in the meantime. Thanks again Klaus

If the spines are frozen, that may be a major part of your noise. The drives shafts need to be able to flex in length. If they do not, the drive shaft is trying to move the axle housing(s) fore & aft. This puts a huge strain on both the pinion shaft assembly & the "U" joints, not to mention the transfer case bearings or engine mounts. Not good. When you do get the splines to move, check the spines themselves for any twisting or steps in them. After 70+ years of use, neither of these scenarios are unusual. Any good drive line shop can replace your splines.

Typically, a frozen slip yoke on a spline is caused by rust or mud (or both) in the inside of the slip yoke. Sometimes the yoke can be removed by hammering the back side of the slip yoke after the dust cap is removed. The driveshaft should be supported in a vise, preferably a chain vise so that the tubing is not distorted.
After the slip yoke is removed the splines need cleaned up and the inside of the slip yoke needs cleaned out. If there is no unusual wear the slip yoke and spline can be put back together and greased well. The assembly should slide easily after being greased. Reinstall the dust cap. If the splines look barrel shaped, it is time for replacement of the splines AND the slip yoke by a competent driveline shop or replacement of the complete shaft. If the splined end is barrel shaped, you can almost guarantee that the slip yoke is worn also. If you replace the splines always replace the slip yoke. Check the condition of the u-joints on both end of the shaft while you are at it. Do not run the driveshaft in a frozen state as this can cause damage to the axle pinion bearings and/or the front transfer case output bearing. Edited by SE Kansas 46 CJ-2A - 24 June 2022 at 9:07pm |

The Frozen shaft will definitely not go back in the car. I tried to hammer out the end but no way … not moving a bit.
We don’t have a Driveline shop over here so I guess I will look around for a replacement. If online has one extra on the shelf, don’t be shy Otherwise, I did a longer ride yesterday and the noise is definitely gone. The PO didn’t pay attention of how the yokes are positioned. I must admit, I also just learnt now, that there is just one way to go. Guess, every day you learn something new Later Klaus

Assuming you have a stock CJ2A here is one possible solution:

unless you are building a show quality restoration. I strongly suggest you look up Tom Woods drivelines on line. His work is bullet proof made in Utah and costs less for a complete deluxe drive shaft with shipping the the local states wanted to rebuild mine.

You didn't go into detail as to what you did to un-spline the drive shaft except to hammer on it. Before I threw it away I would put every effort into getting to apart. There is a good chance that it is still in usable condition, just needs freed up to slide. Many of these old vehicles were never driven in 4 wheel so they tended to freeze up. Many more never got grease like they needed. Does your drive shaft still have the grease zerk? If so will it take grease? If it won't take grease try pumping penetrating oil into it. Hold a hammer on one side of the yoke and hammer on the opposite side with another hammer, not really hard, just good hard taps to help break out the rust. You can also heat the yoke to try to get it to expand, not red hot, just even heat, then try to drive it apart. Use a brass driving bar so that you don't distort the yoke. A picture would help. Good luck!

I took a couple of lengths of grade 8 all thread & made a couple of stout plates and some nuts & just made a cheap driveline compressor / separator tool. Worked great.

This weekend I removed both drive shafts from a Willys P/U I’m overhauling to replace pinion and xfer case seals. Found front drive shaft slip joint frozen.
I did the same, compressed in my press, but used engine hoist to pull apart, hooked one end to the base other end to the lift and pumped it up.
